Overview
Chronic systolic heart failure (CSHF) is a debilitating condition characterized by the heart's inability to pump blood effectively, leading to significant morbidity and mortality 1.Diagnosis
Echocardiography to assess left ventricular ejection fraction (LVEF) <40% 1.
Natriuretic peptide levels (BNP or NT-proBNP) for symptom stratification 1.
Electrocardiogram (ECG) to identify arrhythmias or signs of ischemia 1.
Comprehensive metabolic panel to evaluate renal function and electrolytes 1.Management
ACE inhibitors/ARBs: Reduce mortality and hospitalization; titrate to tolerated dose 1.
Beta-blockers: Improve survival and reduce hospitalizations; target heart rate reduction 1.
MRA (e.g., spironolactone): Adjunctive therapy to reduce mortality 1.
Diuretics: Manage fluid retention and symptoms of congestion 1.
Hydralazine/nitrate combination: Consider in African American patients with refractory heart failure 1.Special Populations
Pediatrics: Heart transplant alone recommended for infants and young children with primary heart disease and concurrent renal dysfunction, avoiding dialysis post-transplant 2.
Comorbidities: Subclinical hypothyroidism (SCH) may impact prognosis; monitor and manage thyroid function in CSHF patients 1.Key Recommendations
Monitor and manage subclinical hypothyroidism in patients with CSHF to potentially improve prognosis (Evidence: Moderate 1).
Consider heart transplantation as a definitive treatment for infants and young children with combined heart and kidney failure, without concurrent dialysis support post-transplant (Evidence: Expert opinion 2).
Implement ACE inhibitors/ARBs and beta-blockers as foundational therapies to reduce mortality and hospitalizations in CSHF (Evidence: Strong 1).References
